Answer:
I2>I1
Explanation:
This problem can be solved by using the parallel axis theorem. If the axis of rotation of a rigid body (with moment of inertia I1 at its center of mass) is changed, then, the new moment of inertia is gven by:
where M is the mass of the object and d is the distance of the new axis to the axis of the center of mass.
It is clear that I2 is greater than I1 by the contribution of the term Md^2.
I2>I1
hope this helps!!
Answer:
0.90m/s²
Explanation:
Given parameters:
Initial speed = 6miles/hr
Final speed = 12miles/hr
Time taken = 3 seconds
Unknown:
Acceleration = ?
Solution:
Acceleration is the rate of change of velocity with time. It is mathematically given as:
Acceleration = 
We need to convert miles/hr to meters/seconds
Initial speed = 6 x 
x 
x 
= 2.68m/s
Final speed = 12 x 
= 5.37m/s
Acceleration = 
= 0.90m/s²
A generator transforms mechanical into electrical, a transformer reduces/increases the voltage of an alternating current, a magnet attracts metal, and a motor converts electrical energy into mechanical energy.
So, the answer is Motor.
Then the time interval during which the rocket engine provides upward acceleration in 2.1s hope this helps have more photos but can’t put them more in brainliest is appreciated
